Design Guide: Products Galvanized After Fabrication
Design and fabrication practices for optimizing the quality of HDG coatings. This guide contains more than 30 full-color illustrations.
Hot-dip galvanizing plays a crucial role in infrastructure projects, providing durable and long-lasting protection against corrosion. Hot-dip galvanized (HDG) steel has been used for over 175 years to protect steel from corrosion and is widely used in the majority of markets supported by the Bipartisan Infrastructure Law (BIL). In transportation, hot-dip galvanizing is employed to safeguard bridges, highways, and other products from rust and degradation caused by exposure to moisture, chemicals, and harsh weather conditions. The galvanized coating acts as a barrier, preventing corrosion and extending the lifespan of these vital structures. Additionally, hot-dip galvanized steel is utilized in the construction industry for applications such as guardrails, lighting poles, transmission towers, and sign supports. These components are exposed to environmental elements and require reliable corrosion protection to ensure their structural integrity over time.
Hot-dip galvanized coatings provide a cost-effective and low-maintenance solution, reducing the need for frequent repairs or replacements. Moreover, hot-dip galvanizing is used in electrical transmission and distribution infrastructure, where galvanized steel structures, such as poles and substation frameworks, offer superior corrosion resistance in various climates. Overall, the use of hot-dip galvanizing in infrastructure projects ensures longevity, sustainability, and cost-effectiveness by mitigating the detrimental effects of corrosion.
